Adding or replacing memory modules
The computer has one memory module compartment. The capacity of the computer can be upgraded by adding a memory module to the vacant expansion memory module slot or by upgrading the existing memory module in the primary memory module slot.
NOTE: Before adding or replacing a memory module, make sure the computer has the most recent BIOS version, and update the BIOS if needed. See Updating the BIOS on page 70.
CAUTION: Failure to update the computer to the latest BIOS prior to installing or replacing a memory module may result in various system problems.
WARNING! To reduce the risk of electric shock and damage to the equipment, unplug the power cord and remove all batteries before installing a memory module.
CAUTION: Electrostatic discharge (ESD) can damage electronic components. Before beginning any procedure, ensure that you are discharged of static electricity by touching a grounded metal object.
CAUTION: To prevent information loss or an unresponsive system:
Shut down the computer before adding or replacing memory modules. Do not remove a memory module while the computer is on, in the Sleep state, or in Hibernation.
If you are not sure whether the computer is off or in Hibernation, turn the computer on by pressing the power button. Then shut down the computer through the operating system.
NOTE: To use a dual-channel configuration when adding a second memory module, be sure that both memory modules are identical.
To add or replace a memory module:
1. Save your work and shut down the computer.
2. Disconnect AC power and external devices connected to the computer.
3. Remove the battery (see Removing a battery on page 35).
4. Remove the memory service cover.
a. With the battery bay away from you, remove the screw (1).
b. Tilt the memory service cover (2) up.
c. Lift the memory service cover away (3).

b. Grasp the edge of the memory module (2), and then gently pull the memory module out of the memory module slot.
CAUTION: To prevent damage to the memory module, hold the memory module by the edges only. Do not touch the components on the memory module.
To protect a memory module after removal, place it in an electrostatic-safe container.
6. Insert a new memory module:
CAUTION: To prevent damage to the memory module, hold the memory module by the edges only. Do not touch the components on the memory module.
a. Align the notched edge (1) of the memory module with the tab in the memory module slot.
b. With the memory module at a 45-degree angle from the surface of the memory module compartment, press the module (2) into the memory module slot until it is seated.

Cleaning your computer
Use the following products to safely clean your computer:
● Dimethyl benzyl ammonium chloride 0.3 percent maximum concentration (for example, disposable wipes, which come in a variety of brands).
● Alcohol-free glass-cleaning fluid
● Water with mild soap solution
● Dry microfiber cleaning cloth or a chamois (static-free cloth without oil)
● Static-free cloth wipes
CAUTION: Avoid strong cleaning solvents that can permanently damage your computer. If you are not sure that a cleaning product is safe for your computer, check the product contents to make sure that ingredients such as alcohol, acetone, ammonium chloride, methylene chloride, and hydrocarbons are not included in the product.
Fibrous materials, such as paper towels, can scratch the computer. Over time, dirt particles and cleaning agents can get trapped in the scratches.

Cleaning procedures
Follow the procedures in this section to safely clean your computer.
WARNING! To prevent electric shock or damage to components, do not attempt to clean your computer while it is turned on.
● Turn off the computer.
● Disconnect AC power.
● Disconnect all powered external devices.
CAUTION: To prevent damage to internal components, do not spray cleaning agents or liquids directly on any computer surface. Liquids dripped on the surface can permanently damage internal components.
Cleaning the display (All-in-Ones or Notebooks)
Gently wipe the display using a soft, lint-free cloth moistened with an alcohol-free glass cleaner. Be sure that the display is dry before closing the display.
Cleaning the sides or cover
To clean the sides or cover, use a soft microfiber cloth or chamois moistened with one of the cleaning solutions listed previously or use an acceptable disposable wipe.
NOTE: When cleaning the cover of the computer, use a circular motion to aid in removing dirt and debris.
Cleaning the TouchPad, keyboard, or mouse
WARNING! To reduce the risk of electric shock or damage to internal components, do not use a vacuum cleaner attachment to clean the keyboard. A vacuum cleaner can deposit household debris on the keyboard surface.
CAUTION: To prevent damage to internal components, do not allow liquids to drip between the keys.
● To clean the TouchPad, keyboard, or mouse, use a soft microfiber cloth or a chamois moistened with one of the cleaning solutions listed previously or use an acceptable disposable wipe.
● To prevent keys from sticking and to remove dust, lint, and particles from the keyboard, use a can of compressed air with a straw extension.
Updating programs and drivers
HP recommends that you update your programs and drivers on a regular basis to the latest versions.
Updates can resolve issues and bring new features and options to your computer. Technology is always changing, and updating programs and drivers allows your computer to run the latest technology available. For example, older graphics components might not work well with the most recent gaming software. Without the latest driver, you would not be getting the most out of your equipment.
